A Continuous Construction Technology of Radiation-proof Room with Special Structure in Hospital

Abstract

The invention discloses a connection construction method of a hospital anti-radiation room with a special structure, and belongs to the technical field of building construction. The method comprises the steps as follows: construction preparation, bundling of thick bottom plate reinforcing steel bars, pouring of thick bottom plate concrete, thick bottom plate maintenance, bundling of section column reinforcing steel bars, supporting of column templates, bundling of thick wall reinforcing ribs and burying of cooling water pipes, bundling of large-section beam reinforcement and burying of cooling water pipes, supporting of beam, column and wall integrated templates, treatment of corner seams, bundling of thick roof plate reinforcing steel bars and burying of cooling water pipes, treatment for nodes of support top templateswith large-section beams, thick walls, section column templates, layered and itemized pouring of thick walls, section columns, large-section beams and support top concrete, layered and itemized pouring and vibration of the section columns and large-section beam concrete, plastering, laitance sweeping, weepage treatment, temperature control of the whole structure, maintenance and finished product protection. With the adoption of the method, the problem that large-wall-thickness concrete is easy to crack is solved, and the structural engineering quality and the anti-radiation capacity of the anti-radiation room can be greatly improved compared with a traditional construction method.

Description

Technical field [0001] The invention belongs to the technical field of building construction, and specifically relates to a continuous construction process for a radiation-proof room of a hospital with a special structure. Background technique [0002] At present, all kinds of radiation-proof rooms in hospitals, such as the radiotherapy room of medical structure, the radiation room of the anti-radiation damage assessment platform, and the anti-radiation laboratory, are a kind of special structure with special functions and special safety requirements. They are mainly large The wall thickness, top wall and ground are fully enclosed and integrated. Therefore, its quality standards and specifications are extremely demanding. At present, the corresponding technical standards have not been established in China. More reference is made to similar construction methods with large volume and thick floor. The radiation-proof room built by this construction method is in its specific Under t...

Therefore, the requirements for its quality standards are extremely high. At present, no corresponding technical standards have been established in China, and more reference is made to the similar construction method of large-volume thick floor. The radiation protection room built by this construction method has a specific Under the environment, the concrete layered interface is easy to crack, and the temperature cracks are easy to appear at the joints, and the quality cannot meet the requirements
